. This invention relates to removable inner tubes or liners for tobacco pipes, cigar and cigarette tubes for absorbing the moist prod ucts resulting from the combustion of the 5 tobacco and which are arranged in'the bore of the said ipes or the like, and are commonly made of a sorbent paper rolled in tubular form, the edge of the exterior petition or layer of each liner being usually cemented in posi- 10 tion.

In practice, the moist products absorbedby these liners in course or; time permeate the substance,'and exude from the exterior sur-- face thereof, sothat, they become friable'and break when being removed and also cause the bore of the pipe or the like to become fouled, and to avoid this disadvantage it has been proposed to provide the tube with a nonpermeable sheath or covering. F J According to my invention I provide absorbent inner tubes of the described kind, and preferably sterilized, with anon-permeable sheath or covering, made of metal foil, rolled or wrapped-around each inner tube and cemented in position. A layer of .gauzefabric may also be arranged between the absorbent material and the non-permeable covering or sheath, which in this case may be in the form of a metal tube.

In practice, the im roved inner tube is advant'ageously made 0 such a length that it lies L I partly in the bore .of the tobacco pipe or like stem and partly in the bore of the mouthiece thereof, these portions of the two bores eing enlargedtoform' a chamber'shouldered at each end to butt against the two ends of the absorbent inner tube;

To enable the invention to be fully under stood I will describe it by reference to theaccompanying drawing, in .whichi- 1 Figure 1 is a longitudinal section of a-tobacco pi eprovided with a liner or inner tube, in accor ance with the invention.

Figure 2 is asectional side view of a v or tion of the liner or inner tube, detached cm the pipe and drawn to a larger scale'than 'Figurel. I m Figure 3 is a cross-section ofthe said liner or inner tube. l

a is the tobacco pipe having the bowl I) and stem 0 provided with the axial passage or bore (1 communicating with the bowl, and e is the mouth-piece having the axial passa e or bore f aligning with the passage d and a so having the spigot g fitting within the socket h in the said stem 0 in the usual manner.v

i isthe liner or inner tube and j is the chamber in the stem and mouth-piece to' re- .ceive the said liner and. which. chamber is to the exterior of the sai I roll hto prevent its breaking when being removed and to prevent the absorbed moisture from contaminatv ing the bore of the pipe or the like.

m, Figures 4 and 5, is the layerof gauze whic I find it advantageous to apply between the absorbent body of the liner and the nonpermeable exterior thereof, which latter, in this case, is shown inthe form of a tube of metal. I
